If you want all your frames to be handled by the same addon, your options are either:

a) Use PitBull, ShadowedUF, Stuf, or another generic unit frame addon. Since it is generic, it is likely that it will not have many specialized features (like DR timers for PvP) and you will need to use plugins. The main advantage of this method is that you can make the frames look and act exactly how you want using an in-game GUI.

b) Use an oUF layout that is specifically tailored for PvP. I don't know of any, but I've never looked, either. If you can find one, this will probably be what you're looking for -- all your frames handled by one addon, with a consistent look and feel, pre-configured with few or no options, and PvP specific features like DR timers. The main disadvantage of this method is that oUF layouts usually do not have any options, so if you want to change anything, you would need to edit the addon's Lua code yourself.
